To all whom it may concern. 7 1

Be it known that we, (incl-ion l'VRlGHT e 1 Cr We av W .g u, ant uLiLLnsLanai RlUIIJLI o. Lens 0. the United States, residing in the city andcounty oi Philadelphia, t'ltate oi? Pennsylvanla, have invented a newand useful lavnip; Block, of which the following is a specihcation.

Our invention consists oi a novel coinstru1ition of paving blocksadapted ,itor streets, roadways, sidewalks floors or walls of build--ings or other purposes where a hard and durable interlocked surttace isrequired, and conipris s but two standard sizes or forms of blocks whichare provided respectively with vertical and inclined walls of suchcontour that when the blocks assembled, their juxtaposed contiguouswalls iii'iterlocir in such a inannertliiat the liability of thecontiguous blocks to shift vertically or laterally under conditions ol'trallic undaise or climatic conditions, is obviated or reduced to aminimum, so that the operative suriiuae of the paving composed of ournovel blocks will tend to remain triiieand level under all tra-iiic andclimatic conditions. i

To the above ends, our invention consists.

limited to the precise arrangement, and or ganization oil theseinstriunentalities as herein shown and described.

Figure 1 represents a perspective view of one of our novel paving blocksin detached position. i

Figures 2 and 3 represent end views of Figure 1 viewed from differentangles.

Figure 4 represents a perspective view of the other paving blockembodying our invention in detached position.

Figures 5 and 6 represent end views of Figure 4, viewed from differentangles.

Figure 7 represents a section of paving showing the manner of assemblingthe blocks seen in Figures 1 and 2.

upper Figure 8 represents an end view in": Figure 7.

Eliinilar numerals of reference indicate corresponding parts.

Referring to the drawings Urn-invention comprises the two standardsifted paving blocks 1 (seen in Figures 1, 2 and and 2 (seen in Figuresl. 5 and whose construction will now he described, reference beingrfirsthad to the hlcclr l, the upper half ol which is composed oi the paralleltop and bottom surfaces 3 and 4:, the parallel vertical upper walls andthe downwardly converged walls 6, said walls rerininating on the centralhorizontal inedian line or plane indicated at T. y

.The lower halit' ol? the block]. is composed of the lower parallelvertical walls 8, and the outwardly inclined or downwardly divergingwalls 9. i

it will be seen from Figures 1, 2, 3 and 8, that the upper parallelvertical walls 5 merge into the lower outivardly inclined or downwardlydiverging, walls 9, while the upper downwardly converging walls 6 mergeinto the lower vertical walls Referring now to the construction of theblock? and to Figures l 5 and 6, said block hast-he top and bottomparallel surfaces 10 i and 11 the upper parallel vertical. walls 12,

and the downwardly inclined or diverging walls 13. The lower portion olthe block 2' is composed of the lower parallel. vertical walls 14: andthe lower downwardly converging walls 15.

The upper vertical parallel walls '12 i'uerge into the lower downwardlyconverging walls on the inedianlinc or plane 16, while the downwardlydiverging walls 13 merge into the lower vertical parallel walls 14 onthe sauce line or plane 16, as is evident from. Figures 4:, 5, 6 and 8.The preferred manner oi assi-inililing the paving will he understood-from lligures 7 and 8, wherefrom it will be seen that the upperinclined walls 6 are contiguous to the upper inclined walls 13 the uppervertical walls 5 are contiguous to the upper vertical walls 12, thelower inclined walls 9 are contiguous to the lower inclined walls 15.,while the lower vertical walls 8 are contiguous to the lower verticalwalls let. A paving thus constructed with our novel blocks having theircontiguous juxtaposed surfaces interlocked as above described will notbe liable to lateral or vertical'displacement, under traffic or climaticconditions, as is evident.

It will be understood that in the laying of our novel pavement, theblocks are arranged in staggered order, as seen in Figure 7, and, ifdesired, the bottom surfaces & and 11 of the blocks may rest on asuitable concrete bed or foundation, which may be any of the concretesor cements ordinarily used for such purposes, and which we have notdeemed it necessary to show or describe in detail.

The paving blocks may be of wood or any other composition of materialwhich will be impervious to moisture, climatic or tratiic conditions,and in case the blocks are of wood, we preferably employ a foundation orcement bed of material possessing the quality of properly unitinginseparably with the wood, so that the whole pavement will form a unitedand solid mass.

In case the pavement is constructed of wooden blocks, it will beapparent that afterthe same have been laid, the surface of the blocksmay be coated with a suitable moisture repelling mixture, which ifdesired may be applied to the block before being laid, or the blocks maybe coated on their under surface with such mixture to repel moisture.

In case the blocks are made of a composition of matterresulting in aproduct akin to cement or concrete preferably in accordance with thedisclosures in a contemporaneously pending application filed by us, itwill be apparent that the foundation or bed above referred to may beomitted or altered to suit requirements, and it will further be apparentthat a paving composed of our novel blocks may, if desired, have afilling of sand, as phalt and similar materials, which may be rammed inplace in the customary manner.

It willof course be apparent that we do not desire to be limited to anyparticular composition of matter in the production of our novel blocks,as the same may be made of any suitable material, according to requirements.

It will now be apparent that we have de vised a novel and usefulconstruction of a paving block, which embodies the features of advantageenumerated as desirable in the statement of the invention and the abovedescription, and while we have in the present instance shown anddescribed preferred enibodiments thereof which will give in practicesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is

1. The herein described paving block, composed of upper parallelvertical walls, upper downwardly conversz'ing walls, lower verticalparallel walls and lower downwardly diverging walls, said upper verticalwalls merging into said lower downwardly diverging walls, and said upperdownwurdl y converging walls merging into said lower vertical walls.

2 The herein described paving block, composed of upper p rallel verticalwalls, upper upwardly converging inclined walls, lower parallel verticalwalls, and lower downwardly converging walls, said upper parallel wallsmerging into said lower downwardly converging walls, and said upperupwardly converging walls merging into said lower parallel verticalwalls.

3. The herein described paving, composed of a plurality of blocks havingupper purallel vertical. walls, upper downwardly converging walls, lowervertical parallel walls and lower downwardly diverging walls, saidblocks being contiguous to a plurality of blocks having upper parallelvertical walls, upper upwardly converging inclined walls, lower parallelvertical walls, and lower downwardly converging walls, the inclined andvertical walls of said blocks being contiguous and said blocks beingarranged in staggered order.
